The new Spur VM memory model supports immediate Characters so that Characters with Unicode code points greater than 255 can be tested via #==, and wide string access is much faster.
This was introduced with Squeak 5.0.
For the binary representation see Spur image format.
A practical example of the effect of immediacy is demonstrated by the deprecation of 'Character characterTable at: 64' in favor of 'Character value: 63'.
